Pontiac This battery bank does not come will any batteries, you must install 18650 3.7v batteries. The bank will change voltage up to 12v with the use of a very small switch on the side, a bit flimsy mine fell off then caught on fire. You can charge the bank with a USB cable. I don't think you could apply heavy loads to it, example boost your car or run scale model. This is the only 12volt Battery Bank I could find, yes it works but not for long.
